摘　　要：对于双吊点卷扬式启闭机,为保证运行时双吊点同步,研制测力张拉装置安装钢丝绳。该装置包括龙门架、一号葫芦、二号葫芦、一号弹簧秤和二号弹簧秤,龙门架的横梁上安装一号葫芦和二号葫芦,一号葫芦下方连接一号弹簧秤,二号葫芦下方连接二号弹簧秤。操作时先将该装置安放在一侧绳鼓处,一号弹簧秤下端连接绳鼓下方钢丝绳,二号弹簧秤下端连接绳鼓上方钢丝绳,调整龙门架和葫芦位置,使葫芦对钢丝绳垂直向上张拉。使用葫芦张紧钢丝绳,记下2个弹簧秤读数,锚固钢丝绳,再用相同方法安装另一侧钢丝绳,安装时做到两侧钢丝绳张拉位置相同、拉力相同,即能做到初始阶段双吊点同步。运行时,只要门槽铅直,设备制造精度符合要求,整个闸门启闭过程两侧钢丝绳将受力均衡。For the double lifting point hoist,in order to ensure the synchronization of the double lifting points during operation,a tension device is developed to install the steel wire rope.The device comprises a portal frame,No.1 hoist,No.2 hoist,No.1 spring balance and No.2 spring balance.No.1 hoist and No.2 hoist are installed on the beam of the portal frame,and No.1 spring balance is connected below the No.1 hoist,the No.2 spring balance is connected below the No.2 hoist.During the operation,the device is placed on one side of the rope drum.The lower end of the No.1 spring scale is connected with the wire rope below the rope drum,and the lower end of the No.2 spring scale is connected with the wire rope above the rope drum.The position of the portal frame and the hoist is adjusted to make the hoist vertically stretch upward to the wire rope.Use hoist tensioning steel wire rope,write down the reading of 2 spring balance,anchor the steel wire rope,install the other side of the steel wire rope in the same way,ensure that the tension position of the steel wire rope on both sides is the same,that is,the synchronization of the two hanging points in the initial stage can be achieved.During the operation,as long as the gate groove is straight and the equipment manufacturing accuracy meets the requirements,the force of the wire rope on both sides of the gate will be balanced during the whole opening and closing process.
